Industrial Air Cooler Finned Tube Bundle with Carbon Steel Tubes

Yuhong Group: Complete Heat Exchanger Solutions – From Components to Full Systems

Yuhong Group Co., Ltd. designs and manufactures a comprehensive range of thermal equipment for global industries. Our core offerings include shell and tube heat exchangers, pressure vessels, air coolers, and a complete supply of critical components: finned tube bundles, U-tube bundles, heat exchanger tubesheets, and all related parts – ensuring full support for new projects and maintenance.

Shown in the attached photographs is one of our air cooler finned tube bundles – captured during site installation, demonstrating our capability to deliver complete air-cooled heat exchanger solutions for process gas and fluid cooling applications.

Product Focus: Air Cooler Finned Tube Bundle – The Core of Air-Cooled Heat Transfer

The air cooler tube bundle (also known as a finned tube bundle) is the heart of any air-cooled heat exchanger (fin-fan cooler). It consists of multiple rows of finned tubes – carbon steel tubes with aluminum fins – arranged in a structural frame with headers for process fluid distribution. Ambient air is forced (or induced) across the finned surfaces by axial fans, removing heat from the process fluid without consuming water.

Based on the images, this tube bundle exhibits:

• Configuration: Finned tube bundle for air-cooled service
• Tube material: Carbon steel (ASME SA179 typical) – providing reliable heat transfer
• Fin material: Aluminum (extruded or wrapped) – offering excellent thermal conductivity and corrosion resistance
• Header arrangement: Distributed inlet/outlet headers for uniform flow distribution
• Mounting: Site installation in progress – ready for connection to fans and ducting
• Construction: ASME/TEMA compliant

• Optimized fin design: We configure fin type, density (fins per inch), and height to match your specific thermal duty, airflow requirements, and allowable pressure drop.
• Extruded or wrapped fins: We offer extruded aluminum fins (maximum durability, corrosion resistance, no thermal contact resistance) and wrapped fins (L-foot or G-foot – cost-effective for clean service).
• Corrosion protection: For coastal or corrosive environments, we offer galvanized steel frames, epoxy-coated headers, and stainless steel tube options.
• Tube material options: Carbon steel (SA179), stainless steel (304/316L), copper alloy (C70600) – selected based on process fluid corrosivity and temperature.
• Header configuration: Single-pass, two-pass, or multi-pass headers available – optimizing flow distribution and pressure drop.
• Thermal expansion management: For high-temperature applications, we offer U-bend tube bundles to accommodate thermal expansion without stressing the header joints.

The bundle shown in your photographs can be configured for either forced draft or induced draft, depending on your site requirements.

When to Specify an Air Cooler Finned Tube Bundle:

• Water is scarce or expensive – air cooling eliminates water consumption
• Remote locations – no cooling water infrastructure available
• Process fluid is suitable for air cooling – not requiring very low outlet temperatures (typically >10°C above ambient)
• Environmental restrictions – no cooling water discharge allowed
• Freeze protection concerns – air coolers can be designed for cold climates with louvers and recirculation

Typical Applications for Air Cooler Finned Tube Bundles

Component-Only Supply – We Also Provide for Maintenance & Spares

If your existing air cooler needs replacement parts, we supply individual components without ordering a complete new bundle:

• Finned tube bundles – direct replacement for existing air cooler frames – built to your drawing
• Heat exchanger tubes – carbon steel (SA179), stainless steel, copper alloy – cut to length, finned or bare
• Headers / manifolds – carbon steel or stainless steel – with or without nozzle connections
• Tubesheets – drilled and grooved per your pattern
• Fins – extruded or wrapped aluminum – to match your original configuration
• Side channels, support frames – galvanized steel for corrosion protection

How to Specify a Replacement Air Cooler Finned Tube Bundle Correctly

To avoid mismatches, we need the following information (send any of these):

1. Original bundle drawing – best option. We duplicate tube count, fin type, fin density, header arrangement, and overall dimensions exactly.
2. Old bundle (physical sample) – we can measure and reverse-engineer a perfect match.
3. Service conditions – process fluid, temperature, pressure, required cooling duty, ambient temperature range.

Common Errors to Avoid:

• Incorrect fin type – extruded vs. wrapped – affects durability and heat transfer.
• Wrong fin density – too few fins reduces heat transfer; too many increases airflow restriction.
• Header nozzle orientation – must match existing piping.
• Corrosion protection – for coastal applications, we recommend galvanized frames and epoxy-coated headers.
• Tube material mismatch – must be compatible with process fluid (corrosion, temperature).

Quality Assurance & Documentation

Every air cooler finned tube bundle we ship includes:

• Material Test Certificates (MTC) – for tubes, fins, and headers
• Hydrostatic test report – verifying tube-to-header joint integrity
• Dimensional inspection report – verifying fit to your equipment
• PMI (Positive Material Identification) – available on request
• Third-party inspection (SGS, BV, TÜV) – at buyer's request
